OSCILLATOR AND TRANSMISSION/RECEPTION DEVICE

WIPO Patent Application WO/2005/004322

A1

There are provided an oscillator and a transmission/reception device which can reduce the manufacturing cost and can be used for wide-range modulation with a high output. On an oscillation circuit substrate (1), an oscillation circuit section (2) and a frequency control circuit section (15) consisting of micro-strip lines (5, 16) and the like are formed. Moreover, on a dielectric substrate (22), a TM010-mode resonator (23) consisting of resonator electrodes (23A, 23B) is formed and excitation electrodes (24, 25) are formed, thereby constituting a dielectric resonator chip (21). The oscillation circuit substrate (1) has a land (19) attached to the resonator electrode (23B) by using a bump (26) while the micro-strip lines (5, 16) are attached to the excitation electrodes (24, 25) by using the bump (26). Thus, it is possible to excite the TM010-mode resonator (23) by using the excitation electrodes (24, 25) and reduce the size of the dielectric resonator chip (21) as well as reduce the manufacturing cost.
